AVERY BABBETT, OF AUBURN, NEW YORK.

MACHINE FOR CUTTING IRREG-ULAR FORMS.

Specification of Letters Patent No. 13,076, dated June 19, 1855.

To all whom t may concern Be it known that I, AVERY BABBETT, of Auburn,of the county of Cayuga and State of New York, have invented a new anduseful Machine for Producing Angular Irregular Forms; and I do herebydeclare that the following is a full and exact description thereof,reference being had to the accompanying drawing and the letters ofreference marked thereon.

The nature of my invention consists in working a series (two or more) ofrot-ating cutters of any form, in combination with a carriage and ointsso arranged as to enable the workmen to present the material to bewrought upon, to the action of said cutters in any desirable position,alternately.

To enable others skilled in the art to make and use my invention I willproceed to de scribe its construction and mode of operation.

A, A, A, A, Figure 1 is an iron frame work supporting the several parts;B, B, B, B, B, B, are six frames, having each a shaft C, C, C, C, C, C.Boxed on the top of each and projecting toward the front side of themachine, and on the ends of said shafts so projecting, are designed tobe placed disks and knives, one of which is shown at D, showing themanner of holding and making the same. The several frames B, B, &c., aremade adjustable vertically by means of the slots through which pass thebolts E, E, E, E, E, E, corresponding to those or other slots and boltson the back side,-said bolts serving to secure the frames B, B, &c., tothe main frame A, A, A, A.

On the front of the machine, Fig. 1, F, F, are the ways, on which thecarriage G, Gr, slides, by means of the crank H, shaft I, pinion J, andrack K. The vertical shaft L (the lower end of which is shown at L)extends upward from this point and terminates in a joint on each side ofthe frame M, M,-allowing said frame work to vibrate by means of saidjoint, and is held in a. horizontal position by means of the index N,and spring O.

The shaft P, extends through the shaft Q, and terminates in a plate intowhich is inserted the two spurs R, R. Between said spurs and the pointS, is placed the material to be wrought, and by means of the hand wheelT, the spurs R, R, are driven forward into it, thus securing it in afixed position relatively to the shaft Q.

The index U, is keyed fast to the shaft Q, and extends through thebearing toward R, R, and from the lower side of said shaft, is projecteda plate V, on which the material to be wrought is rested to prevent itfrom turning or changing its position relating to the shaft Q, while inthe process of being wrought. The index W, is made fast to the shaft L,close under the frame M, M, and is held firm in position by means of thespring Y. The indeX U, is held in position by means ofthe spring Z,extending to the right of Z, as shown by dotted lines behind the handwheel T, and is secured to a stud A', (also shown in dotted linesg) saidstud is bolted fast to the under side of the frame M M at B. The threeindexes M, U, WV, are spaced and marked into degrees corresponding totheir respective radi, in the full size machine, and when the springs O,Z, Y, are each placed at 0, in their respective indexes (or the pointfrom whence the degrees are numbered,) the shaft Q, and-the point S,being on the same line, are horizontal, and at right angles to the waysF, F, and parallel to the cutter shafts C, C, C, C, C, C.

Now let it be supposed that the cutter shafts were fitted with cuttersand running as follows: Shaft No. 1, with cutters suitable to producethe form between figures 1 2, and 1-2, Fig. 2, the bottom of the cutterdisk running tothe left. Shaft No. 2, with cutters of suitable form tocut the edge of the facet between the lines E', F, bottom of cutter diskrunning toward the right. Shaft No. 3, with cutters suitable in form toproduce the top of the foot, from the lower end of the pillar, as shownby the line D, to the end thereof at H', lower edge of disk platerunning toward the left. Shaft No. 4, with cutters the same in form asNo. 2, but the disk plate running in the opposite direction, lower edgeto the left. Shaft No. 5, with cutters suitable to produce the form ofthe under side of the footthe lower edge of disk running toward theleft. Shaft N o. 6, with cutters suitable to cut the form of the edges,from F to H, lower edge of disk running to the left. In Figs. 2 and 8will be found samples of work. The column, or pillar terminates at thejoint out of which springs the line D,-all below this joint is the workof the machine above described.

H is one of the four feet. They are jointed together as represented atFig. 2,- the line over the letter E', represents one of said joints.

Commencing with the carriage between the cutter shafts Nos. 2, and 3,with a suitable piece of material secured in its proper place as abovespecified, the mode of operation will be as follows. Lifting the springY, from t-he index W, the end of the frame M, M, opposite to the one inwhich the material to be wrought is placed, (which will be after thiscalled the front end) must be carried around to the left 23O where itwill be held lirm by said spring. Then the spring` Z should be raisedout of its notch from the under side or edge of the index U, and bymeans of a handle I, secured to the index, (shown in dotted lines behindthe hand wheel T,) the said index should be turned so as to place thespring to the left of Oo a distance equal to 90D. Then by means of thecrank H, the carriage should be moved under the cutter shaft No. 2, anda like form as that represented in Fig. 2, between the lines over theletters E, and F will be produced on the opposite edge of the foot H',Fig. 2. The ovolo, and horizontal space between it and the vertical edgeof the foot, between the figures 1-2 and 1-2, is the next in order. Toaccomplish this, the frame work M, M, see Fig. 1, should be carried 39045 from 0, on the index lV, to the right. The index should be set 180,20 from OO, to the left, and the index N should be set 5, 15' from 0",by raising the front end of the frame work M, M, this distance. Theindices thus set will bring the parallel lines between the figures 1--2,over the letters E, F (see Fig. 23) parallel to the ways F, F, Fig. 1,and when the work is passed under the cutters on the shaft No. 1, therefuse wood is cut away and the form produced, on the side over theletters E, F. To cut the opposite side the frame M, M, Fig. 1 should becarried around toward the right by setting the index 39C, 4.5 to theleft of 0;.

and the index U, should be changed from 18", 20 on the right of OO, to18, 20 on the left, and the work moved back under the same cutter shaft,and the opposite side will be cut. y

To cut the top of the foot, all the indices must be restored to 0O andthe work passed under the cutter shaft No. 3, which will cut the wholeof the form of the top, bringing the same quite under the pillar (see Fig. 2).

The vertical curved surface included between the two vertical lines overthe letters E, F, is next (see Fig. 2). To accomplish this the frame M Mshould be moved to the right 23o, by means of the index XV, from 0, andthe lower edge of the index U, should be turned to the left of 0"-90oand the work passed under the cutter shaft No. 4. To cut the botto-m orunder side of the foot, the index WV, should be set at OO, the index N,at OO, and the index U at 90O from 00, and the work passed under theshaft No. 5. To cut the two edges from the line over F to the end of thefoot at H, is the last (see Fig. 2). To accomplish this the indices N,and "W are placed at 0, and the index U, set at 90O from 0",y and passedunder the cutter shaft No. 6, and then turned to the opposite side of.OO, the same distance and the work is completed.

From the above it will be seen that a great variety of angular,irregular forms, may be produced by the machine above specified, bysimply changing the form of the cutters or knives and varying thesetting of the indices.

What I claim as new, and desire to secure by Letters Patent is- Themachine herein specified for the purpose of producing angular irregularforms substantially as herein set forth.

AVERY BABBETT.
